The invention relates to a profiled rail for supporting plate-shaped elements, particularly for inlay mounting of ceiling plates for louvered ceilings. The profiled rail comprises a base body, which is provided, at least in areas with a T-profile and which has a longitudinally extended web as well as a lower flange. The lower flange is placed along a longitudinal edge of the web and comprises two lower flange sections each extending from the web essentially in opposite directions. The lower flange is formed by bending the web, and the side of the lower flange, which is oriented away from the web, is provided with a facing board. A multitude of openings are provided in the web, whereby at least one of the lower flange sections is formed by material sections of the web that are folded out from the openings, and the web is provided as a single layer essentially over its entire surface. The invention also relates to a method for producing a profiled rail of this type.
